Answer:
756 is a reasonable estimate because the proportion of the sample whose favorite pizza is pepperoni is about 27 %
Step-by-step explanation:
given data
random sample = 150 people
favorite pepperoni pizza = 40
total of residents = 2800
number of residents favorite pizza = 750
solution
we get here first Proportion favorite pizza that is
Proportion =
Proportion = 0.27 = 27%
and now we get 27% of total of residents that is = 27% × 2800
= 756
so we can say 756 is a reasonable estimate because here proportion of an sample whose favorite pizza are pepperoni pizza about 27 %
Answer:
B is the most reasonable answer
Step-by-step explanation:
btw 9% of 578 is 52.02, so it works
Answer/Step-by-step explanation:
✔️Reference angle = 50°
Opposite side length = y
Hypotenuse = 8 cm
Adjacent = x
Thus, applying CAH we can find x as shown below:
Cos 50 = adj/hyp
Cos 50 = x/8
8 × cos 50 = x
x = 5.1 (to 1 decimal point)
Thus, applying SOH, we can find y as shown below:
Sin 50 = opp/hyp
Sin 50 = y/8
8 × Sin 50 = y
y = 6.1 (to 1 decimal point)
